You can view the container's log through the docker logs command.

Command format:

$docker logs [OPTIONS] CONTAINEROptions:--details displays more information-- f,-- follow tracks real-time logs-- since string displays logs since a certain timestamp, or relative time, such as 42m (that is, 42 minutes)-- how many lines of logs are displayed by tail string from the end of the log, default is all-t,-- timestamps displays timestamps-- until string displays logs before a certain timestamp, or relative time, such as 42m (that is, 42 minutes)

For example

View the log after the specified time and display only the last 100 lines:

$docker logs-f-t-since= "2019-08-08"-tail=100 CONTAINER_ID

View the log for the last 30 minutes:

$docker logs-- since 30m CONTAINER_ID

$docker logs-- tail 20
